Add more accurate logging for stats log loss.

+ Only record eventual failure after the retries to get a accurate log loss count.
+ Record all types of failures which lead to log loss
+ Change the timestamp from elapsedRealtime to wallclock time for easier debugging server side
+ Also log the count too.
